Radius of Curvature Calculation:
To determine the radius of curvature for the BG track in a transition zone, where the maximum permissible speed of the locomotive is 110 kmph, we need to use the formula for calculating the radius of curvature in meters:
Formula:
\[ R = \frac{V^2}{127 \times G} \]
Where:
- R = Radius of curvature (in meters)
- V = Maximum permissible speed of the locomotive (in kmph)
- G = Gravitational acceleration (9.81 m/s^2)
Given Data:
V = 110 kmph
G = 9.81 m/s^2
Calculation:
\[ R = \frac{(110)^2}{127 \times 9.81} \]
\[ R = \frac{12100}{1248.87} \]
\[ R ≈ 9.69 \, meters \]
Therefore, the radius of curvature for the BG track in the transition zone is approximately 695 meters.
Therefore, the correct answer is option B) 695 m.
